PATENT HARRY BOARDMAN INGRAl-IAM, OF BOSTON, MASSACHUSETTS, ASSIGNOR TOTHE STAPLE IIEELING COMPANY, OF SAME PLACE.

MACHINE FOR ATTACHING HEELS TO BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 582,502, dated May 11,1897.

Application filed April 11, 1896. Serial No. 587,087. (No model.)

To all whom it may concern:

Be it known that I, HARRY BOARDMAN IN- GRAHAM, of Boston, county ofSuffolk, and State of Massachusetts, have invented an Improvement inMachines for Attaching Heels to Boots or Shoes, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

The machine to be herein described is especially adapted to drivefastenings from the interior of the sole into the heel, and myimprovements are such as to enable small boots and shoes to be operatedupon, the heel being held in a clamp and the post carrying the boot orshoe and the driving mechanism be ing reciprocated vertically to effectthe insertion of the fastenings.

One part of my invention in a machine for attaching heels t0 boots andshoes consists in a post and a driver-plate combined with a latch toconnect the said plate and post, substantially as will be described.

Other parts of my invention will be hereinafter described, and claimedat the end of this specification.

Figure 1,in front elevation,partially broken out, shows a machinecontaining my improvements; Fig. 2, a right hand side elevation thereof;Fig. 3, an enlarged sectional detail of some of the parts with the heelclamped ready to have the fasteners driven to attach the heel to thesole, which is partially shown; Fig. 4, an under side View of theheel-holder, and Fig. 5 a detail showing the means employed fordetermining the operative position of the post.

The base-frame A sustains in suitable bearings a power-shaft A, providedwith suitable fast and loose pulleys and a balance-wheel, said shafthaving a pinion A which engages a gear A fast on a shaft A provided atits end with a suitable crank-pin A, which by a link A is connected to astud A fast on and so as to reciprocate the cross-head A up and down onthe guide-rods A entering at their upper ends a block A The cross-head Ais provided with a guideway B, which is engaged by the foot B of a postE the cross-head having mounted on it a stop B shown as a cam pivoted atB and having a handle B the latter being provided with a set-screw B,which enters a block B located in a groove at the under side of the cross-head. (See Fig. 3.)

By turning the handle when the set-screw is loose the stop B may be putin just the proper position to stop the post having on it a boot or shoewhen pushed under the heel held by the heel-holder to be described, thetightening of the screw locking the stop in place.

WVhen the post is pushed back into working position, it will remainthere and be held frictionally by the engagement of the guide betweenthe shims in the post, a handled screw a, carried by the foot, abuttingagainst one of the shims at one side of the guide.

- The post is hollow, as best shown in Fig. 3, and is threadedinternally at h'to receive an adjusting device I), on which rests aspring 5 which sustains a block n, which supports the lower end of a rod19 connected to the fastening-carrier b composed of a box and a topplate provided with holes for the reception of fastenin gs herein shownas staples.

The rod b above the post enters loosely a hole in the driver-plate bhaving an attached series of drivers If, the said plate resting by itsflat side on the small upper end of said post and being connectedthereto by a suitable catch, shown' as a latch 19 in engagement with aprojection b fast on the driverplate, the latch being shown as actuatedby a spring Z9 Heretofore in this class of machine the driver-plate hashad at its under side a hub to enter a hole in the upper end of thepost, and it was fastened in place by pins passed through the post andentering grooves at the side of the hub, and owing to the great strainexerted by the machine the post has had to be quite thick, and the huband top have required so much room for strength as to preclude thereduction of the driver-plate and post to a size small enough for smallshoes.

In the drawings I have shown a large sized driver-plate applied to thetop of the post, butfor small shoes the dri ver-plate used may and willat times be as small as the top of the post, and if the post had to beof sufficient diameter to receive a hub at the lower side of thedriver-plate, as heretofore, it will be obvious that a post having awall at its top of sufficient thickness to properly hold the driverplatehub could not be made nearly as small as when a catch is used to holdthe driverplate on the post. Heretofore the fasteningcarrier has beenmounted loosely on the end of a stud inserted in a hole in the post andsurrounded by an adjustable collar and a spring.

The heel c, to be attached to the sole 0 of the shoe, (partially shownin Fig. 3,) is held between jaws o of a heel-holder, said holder beingcomposed of two jaws pivoted on a stud 0 depending from an arm a of aplate 0 having a guide 0, adapted to enter a guideway in the head a of arod 0 entering a verticallyadjustable sleeve 0 and surrounded by aspiral spring 0 one end of which abuts against an adj usting-nut a Thejaws have ears f, to which are connected the ends of a suitable springf, to normally close the jaws onto the heel. The jaws have pivoted tothem two radius-bars f f jointed to each other by a pin f, the pinentering a slot f in the arm 0" and sliding therein and acting as aguide for said jaws to enable them to open and close uniformly from acommon center. The tread end of the heel bears against the bottom orunder face of the plate 0 The nut c has a hand-wheel 0 by which it maybe turned, the said nut, rod, &c., being substantially the same as in myformer patent, No. 486,288, dated November 15, 1892.

In the use of the machine herein described the operator will putsuitable fastenin gs into the fastening-carrier, the post being drawnout from under the plate 0 and will apply the shoe to the post with thesole uppermost. The heel will be placed in the heel-holder,and theoperator willthen push the post and shoe into its operative position andstart the machine, and the cross-head will be lifted, rais ing the shoeagainst the heel, and thereafter further upward movement of thecross'head will cause the drivers acting on the fastenings to drive themfrom the carrier through the sole and into the heel.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. In a machine for attachingheels to boots and shoes, the combinationwith the post, fastening-carrier, and usual connections, of adriver-plate between the post and fastenin g-carrier, and means toinstantly throw said plate and post into or out of rigid engagement,said means comprising a latch and a projection carried respectively bysaid parts and arranged to interlock, substantially as described.

2. In a machine for attaching heels to boots and shoes, a post, a springtherein, a screw to support and adjust said spring, and a fastening-carrier having an attached rod inserted in said post and supported bysaid spring, combined with a driver-plate, a series 01": drivers carriedthereby and entering said fasteningearrier, and a catch to connect saidpost and driver-plate, substantially as described.

3. In a machine for attachingheels to boots and shoes, a hollow postthreaded internally, a screw inserted in said hollow post, a springsupported by said screw, a block resting on said spring, and arodsustained by said block and having attached to it a fastening-carrier,combined with a driver-plate surrounding said rod at the top of saidpost and containing a series of drivers, said driver-plate and rod beingremovably secured together by means of a recess formed in one, aprojection on the other to enter said recess, and a catch to engage andhold said projection in said recess, substantially as described.

4. In a machine for attaching heels to boots and shoes, the head 0 itsattached plate having an arm, and a pair of heel-holding jaws pivoted onsaid arm, combined with a spring to close said jaws, and a toggle-jointhaving a pin to cooperate with said arms to insure equal movement ofsaid arms in opening and closing, substantially as described.

5. In a machine for uniting heels to boots and shoes, a post, a springtherein, a fastening-carrier having an attached rod entering said postand sustained by said spring, a driver-plate resting with its fiat sideon the top of said post, a catch to confine said driverplate to saidpost, a series of drivers, and a head 0 combined with a heel-holdercomposed of two pivoted arms, a connected spring, and devices connectedto said arms to insure the equal movement of said jaws in closing andopening, to adapt themselves to heels of difierent sizes, substantiallyas described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
